To investigate the recognition and approach of the hidden related vascular in hemifacial spasm patients during the operation of microvascular decompression.
The clinical records of 85 patients of hemifacial spasm were analyzed at our hospital. The hidden related vessel was found in 7 patients. REZ (root entry zone) was surrounded by Teflon cotton slice to separate the vessel from REZ.
There were 7 patients of hidden related vessel in 85 patients. And the related vessels were anteroinferior cerebellar artery and its branches. The symptoms became totally relieved after operation and there was no recurrence.
The microvascular decompression is an effectively treatment for hemifacial spasm patients. Searching for the related vessel (particularly hidden related vessel) is the most important part of the operation. An effective decompression of REZ is the key point of operation.
